WIN DING-MACHINE.

Specification of Letters Patent.

Patented Jan. 5, 1909.

T o all whom 'it 'may concern:

Be it known that I, PIERRE VINDRIER, a citizen of the French Republic,residing at Lyon, in the French Republic, have invented certain new anduseful Improvements in Winding-Machines, of which the following is aspecification.

The improvements in winding machines which form the object of thepresent invention have for their purpose to allow of obtaining tightlycross-wound cops which do not become unwound by the eifects of theimpacts of the shuttle, and the invention also has the advantage ofconsiderably increasing the amount of thread in a cop of given size.These results are obtained by substituting for the ordinarythread-guides a roller which continuously rubs against the cop to beproduced, whatever may be its size, this roller having formed around itan oblique groove destined to impart to the thread, by the rotation ofthe roller, a very rapid reciprocating movement combined with themovements common to other winding machines.

The annexed drawing shows in Figure 1 an elevation and in Fig. 2 aplan-view of an element comprising a thread-guide and spindle. Fig. 3 isa detail view of a modification of the roller. Figs. 4 and 5 arerespectively a plan and side view of the mechanism for impartingmovement to the yarn guide. Fig. 6 shows a dtail of mechanism forvarying the speed of the movements imparted to the yarn guide.

Each element comprises a guide-support A fixed by a bolt and nut B to acommon bar O extending all along the machine and fixed at its two endsto a slide D having a double vertical movement, namely a continuous slowmovement from bottom to top and a reciprocating movement of greater orless amplitude. Both these are obtained by the ordinary known means andare suiliciently indicated by the three arrows upon the slide D in Fig.1.

The guide-support A is traversed with slight friction by a bar E bent atone end at E1 and soldered at the other to a socket F on which turns aroller Gr having on its circumference an oblique groove I-I, or inclinedplane H1. This roller normally bears against the spindle I owing to theaction of a spring J surrounding a rod K iixed to the bent end E1 of thebar E and extending with slight friction through a hole E2 provided in alug A2 at the front part of the guide-support A.

The tension of the spring J is regulated' by a small compressing nut Lto which an arm M is fixed to prevent its rotation. The arm M bearsagainst the guide A. The forward or rearward movement of this nut L isproduced by turning the rod K, which is threaded on part of its lengthat L1. At its opposite end the said rod is provided with a notch K1,which, when the rod is moved towards the left, engages the hole E2formed in the lug A1 of the guide-support A and thus retains the rollerGr at a distance from the spindle to allow, for example, of mending abroken thread.

For removing the cops when finished, it is suicient to lower the slide Din the ordinary manner. The bent, left-hand parts E1 of the bars E ofall the elements are then acted on by a series of inclined planes N xedto a table O, and the rollers are simultaneously removed from therespective cop-spindles.

The end-position of the bar E is limited by a small nut P, screwed uponand serving also as means for securing in place the end of a bent wire Qwhich is carried by the bar E and forms at the same time a ring forguiding the thread coming from the bobbins.

The several movements of the yarn guide are produced by means of themechanism shown in Figs. 4, 5 and 6. In Fig. 4, 1 is a driving pulleyfixed to a shaft 2, to which is also fixed a cone pulley 3. The latteris geared by a belt 2O to a cone pulley 4 loose on a shaft 5. A spurwheel 6 is fixed to the pulley 4 and meshes with a spur wheel fixed to acounter shaft which is connected by a train of gear S, 9, 10 to theshaft 5. To thc shaft 5 is fixed a worm 11, which engages worm wheels 12and 13 fixed to vertical shafts 14 and 15 respectively. To the shaft 14is fixed a cam 16 (Figs. 4 and 5), rotation off which impartsreciprocating movement to the slide D carrying the bar O. This movementis transmitted to the slide D by means of a chain 21 attached to a lever22 which is fulcrumed at 23 and carries a roller 24 resting on the cam16. The said chain is also attached to a drum 25, and

. 36 xed to a shaft 37. The drum 25 to which the chain 21 is attached isalso xed to the shaft 37, so that the rotation imparted to the latter bythe worin gears causes the chain to be slowly wound on the drum. Thepull thus exerted on the chain gradually moves the levers 2S and rollers26 and 27 into the positions indicated by dotted lines in Fig. 5, and bythis means the shaft 29 is slowly rotated to lift the slide D. Duringthis lifting movement the rotating cam 16 alternately lifts the lever 22and allows it to descend to normal position by gravity. The lifting ofthe lever 22 and the consequent yielding of the chain enable the weightof the slide D and parts xed thereto to rock the shaft 29 through acertain angle; the lowering of the lever 22, and Ythe draf exertedthereby on the chain, cause the sha 29 to rock through an angle in theopposite direction. This rocking movement is additional to the slowrotation imparted by the drum 25, so that the slide D receivesreciprocatory motion simultaneously with its upward feed motion. Theshaft 15 rotated by the worm wheel 13 has a crank arm 17, the pin 18 ofwhich engages A,a slotted arm fixed to a slidable ban The latter hasprojections engaging the belt 20 on the cone pulleys 3 and 4, so thatduring the longitudinal displacement of the bar 19 by the crank arin 17the belt is shifted on the said pulleys. By this means the speed of theshaft 5 and worm gears is gradually altered forthe purpose of impartingthe desired conical shape to the cops.

When the machine is started the rollers G bear against the spindles I,which, owing to their continuous rotation, rotate the said rollers. Ashas been statedthe latter have a reciprocating movement of suitableamplitude combined with a slow upward displacement. Since, however, thegrooves I-I encircling the rollers are inclined with regard to the axesof the latter, it follows that the threads passing through the saidgrooves receive ,a third movement of rapid reciprocation, the amplitudeof which is equal to the distance between the highest and lowest pointsof the inclined grooves in the rollers. This third movement is ofconsiderable importance, since it imparts a close crossing of specialpattern which assists in preventing the disintegration of the cop.Moreover, the fact that the roller G to secure by Letters Patent of theUnited l States is 1.
